Description

Technical Field

[0001] The present invention relates to the technical field of cryoablation, and in particular to a cooling system and a cooling method. Background Art

[0002] Cryoablation is a commonly used treatment method in the field of medical devices, mainly used to treat tumors and other abnormal tissues. The system used for cryoablation treatment in the prior art is usually composed of components such as a refrigerator, a cryoprobe, pipelines and control systems. The cold source fluid (for example, liquid nitrogen, argon and helium, etc.) is delivered to the treatment area through the cryoprobe at an appropriate rate and pressure to reduce the temperature of the treatment area, thereby achieving cryogenic destruction of abnormal tissues. In the current cryoablation technology, efficient cold transfer is one of the key factors to ensure the treatment effect.

[0003] However, the cooling systems in the prior art generally adopt a single direct cooling method or a simple heat exchange design. For example, the invention patent with publication number CN102014777B discloses a system and a method for using the system to cool the cryo tip at the distal end of the probe for a cryoablation procedure. In particular, the cryo tip is cooled to a cryogenic temperature by a liquid refrigerant to perform a cryoablation procedure on biological tissue. The refrigerator will include a pressure vessel for holding the liquid cryogen. Thus, a portion of the cold inlet line connected to the container in fluid communication with the cryoprobe is curled and immersed in the liquid cryogen.

[0004] The above-mentioned prior art cools the pipeline (or "pipe") by immersing it in a refrigerant. In the process of transmitting the cold source fluid through the pipeline, the refrigerant near the cold source may freeze when the temperature drops to a certain level, thereby affecting the transmission of cold to the pipeline.

[0005] Therefore, there is an urgent need for a cooling system and a cooling method that can effectively transfer cold to the pipeline to solve the above problems. Summary of the invention

[0014] According to the present invention, in some schemes, the conductive section partially extends into the interior of the main body along the axial direction, the pipe unit is circumferentially wound around the support portion from top to bottom along a first direction and radially arranged outside the groove to form an outer ring portion, and the end of the outer ring portion is folded back along a second direction opposite to the first direction to form an inner ring portion wound around the support portion from bottom to top and radially arranged inside the groove;

[0015] The outer ring portion extends out of one end of the shell to form an inlet portion, and the inner ring portion extends out of one end of the shell to form an outlet portion.

[0016] According to the present invention, in some schemes, the refrigeration device includes: a cooling generator, a conduction seat configured on the cooling generator and connected to the shell, the conduction seat constructs the conduction section, and the part of the conduction section extending into the interior of the main body forms a conduction head.

[0017] According to the present invention, in some aspects, the pipeline unit is configured as at least one cooling pipeline or is configured as a plurality of cooling pipelines arranged in parallel.

[0018] According to the present invention, in some aspects, the main body is provided with a plurality of the support parts at equal intervals along the circumferential direction, and the shell is constructed with cooling rods that penetrate the support parts along the longitudinal direction and are formed between the outer ring part and the inner ring part.

[0019] According to the present invention, in some solutions, a side of the shell connected to the refrigeration device forms an insulation chamber for accommodating a portion of the conduction section.

[0020] Based on the same inventive concept, the present invention also discloses a cooling method for a cooling system, comprising the following steps: Step S1, starting a refrigeration device to generate cold energy, and introducing the cold energy into an energy conversion component through a conduction section;

[0021] Step S2, guiding the cold source fluid into the pipeline unit, the cold source fluid flows around the energy conversion component in the pipeline unit, and transfers cold energy to the pipeline unit through the energy conversion component to reduce the temperature of the cold source fluid;

When the refrigerant in the cooling system freezes at a certain temperature, the cold can still be transferred to the pipeline unit through the energy conversion component, thereby avoiding affecting the cold transfer to the pipeline unit.

[0035] In order to make the purpose, technical solution and advantages of the technical solution of the present disclosure clearer, the technical solution of the embodiment of the present disclosure will be clearly and completely described in combination with the drawings of the specific embodiments of the present disclosure. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments.

"Inside", "outside", "upper", "lower", "far", "near", "front", "back" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly. The drawings in this disclosure are not strictly drawn according to the actual scale, and the specific size and quantity of each structure can be determined according to actual needs. The drawings described in this disclosure are only schematic diagrams of the structure.

[0037] Please refer to Figures 1 to 11 A specific implementation of a cooling system and a cooling method provided by the present invention. Wherein, "axial" means Figure 3 The direction indicated by the axis Q of the energy conversion assembly 20. "Longitudinal" means a direction parallel to the axial direction.

[0038] Ginseng Figures 1 to 3As shown, the cooling system 100 includes: a refrigeration device 10, a shell 30 configured in the refrigeration device 10, an energy conversion component 20 arranged in the shell 30, and a pipe unit 40 circumferentially wound around the energy conversion component 20; the refrigeration device 10 is constructed with a conduction section 11 extending into the shell 30 to transfer cold to the energy conversion component 20; the energy conversion component 20 includes: a main body 21, the main body 21 is formed with a plurality of support portions 22 spaced apart along the circumferential direction, and a through groove 29 extending along the axial direction is formed between adjacent support portions 22; the pipe unit 40 is wound around the support portion 22, and the support portion 22 is at least partially recessed radially inward to form a groove 23 for accommodating the pipe unit 40. The shell 30 contains a refrigerant, the energy conversion component 20 and the pipeline unit 40 are immersed in the refrigerant, and the refrigeration device 10 transfers cold energy to the energy conversion component 20 through the conduction section 11. The energy conversion component 20 can transfer cold energy to the pipeline unit 40 and the refrigerant. The temperature of the refrigerant is lower than the temperature of the cold source fluid (for example, nitrogen, argon and helium, etc.) transmitted in the pipeline unit 40.

[0039] The energy conversion component 20 can transfer cold to the pipe unit 40 and the refrigerant through the support portion 22, the through groove 29 and the groove 23, which helps to distribute the cold and maintain the refrigerant in a suitable low temperature range to prevent freezing. The contact area between the support portion 22 and the pipe unit 40 can be increased by the groove 23 to promote the heat exchange efficiency between the energy conversion component 20 and the refrigerant fluid in the pipe unit 40, thereby ensuring that the cold can be more effectively transferred from the energy conversion component 20 to the refrigerant fluid in the pipe unit 40, thereby improving the cold transfer efficiency. The cooling system 100 solves the problem in the prior art that when the refrigerant freezes at a certain temperature, the cold transmission to the pipe is affected. When the refrigerant freezes at a certain temperature, the cooling system 100 can still transfer the cold to the pipe unit 40 through the energy conversion component 20, thereby avoiding affecting the cold transmission to the pipe unit 40. The reason is that at low temperatures, the refrigerant will solidify and freeze. If there is no energy conversion component 20, simply winding the pipe around the copper column, because the copper tube is hollow inside, when the refrigerant between the copper column and the copper tube solidifies at low temperature, the wound copper tube cannot efficiently transfer the cold to the refrigerant in the barrel, resulting in the inability to effectively transfer the excess cold to other refrigerants. The solidified refrigerant forms an obstacle to the transfer of cold.)

[0040] In one embodiment, preferably, reference Figure 2 and Figure 3 and Figure 4As shown, the groove 23 is configured as a spiral groove 24 that circumferentially surrounds the side wall of the support portion 22 and is arranged in a spiral shape along the axial direction. The pipe unit 40 is circumferentially wound in the spiral groove 24, and the spiral groove 24 can more fully surround the pipe unit 40, so as to increase the contact area between the pipe unit 40 and the energy conversion component 20 through the spiral groove 24, increase the surface area of ​​heat exchange between the support portion 22 and the pipe unit 40, and help distribute the cold energy over the entire length of the pipe unit 40, so that the energy conversion component 20 transfers the cold energy to the pipe unit 40 more efficiently.

[0041] In some embodiments, illustratively, Figure 5 and Figure 7 and Figure 8 As shown, the groove 23 is configured as a plurality of annular grooves 25 circumferentially arranged on the main body 21, and the annular grooves 25 are arranged at equal intervals in the longitudinal direction. The pipe unit 40 is circumferentially wound in the annular groove 25, and the contact area between the pipe unit 40 and the energy conversion component 20 can also be increased through the annular groove 25, so that the cold energy can be quickly transferred from the energy conversion component 20 to the refrigerant fluid flowing in the pipe unit 40, thereby improving the overall heat exchange efficiency.

[0042] In some embodiments, illustratively, Figure 6 As shown in FIG. 1 , the groove 23 is configured as a spiral groove 24 that circumferentially surrounds a portion of the side wall of the support portion 22 and is arranged in a spiral shape along the axial direction, and a plurality of annular grooves 25 that are circumferentially arranged on the main body 21. When a plurality of annular grooves 25 are configured, they are arranged at equal intervals along the longitudinal direction. It should be noted that the spiral groove 24 and the annular groove 25 are arranged in the same order along the longitudinal direction, and the spiral groove 24 can be as follows: Figure 6 As shown in the figure, the annular groove 25 is formed in the longitudinal direction above the annular groove 25. The annular groove 25 can also be formed in the longitudinal direction above the spiral groove 24 (this state is not shown). The spiral groove 24 and the annular groove 25 can also be staggered in the longitudinal direction (this state is not shown), as long as it can be realized for the circumferential winding of the pipeline unit 40. Through the composite structure design of the spiral groove 24 and the annular groove 25, the contact area between the energy conversion component 20 and the pipeline unit 40 is increased, and the efficiency of the energy conversion component 20 to transfer the coldness to the pipeline unit 40 is improved.

[0043] Further, Figure 2 and Figure 3 and Fig.10 As shown, the conductive section 11 extends partially into the body 21 along the axial direction, and the pipeline unit 40 extends along the first direction (eg Figure 3 The outer ring portion 41 is wound around the support portion 22 from top to bottom in the circumferential direction (indicated by the arrow Q1 in the middle) and is radially arranged outside the groove 23 to form an outer ring portion 41. The end of the outer ring portion 41 is along a second direction (such as Figure 3The outer ring portion 41 extends out of one end of the housing 30 to form an inlet portion 411, and the inner ring portion 42 extends out of one end of the housing 30 to form an outlet portion 421. Fig.10 The part of the pipe unit 40 framed by the dotted line frame C1 is the outer ring 41, and the part of the pipe unit 40 framed by the dotted line frame C2 is the inner ring 42. By inserting the conduction section 11 deep into the main body 21, it is ensured that the cold energy generated by the refrigeration device 10 can be directly and efficiently transferred to the central part of the energy conversion component 20, so as to facilitate accurate control and adjustment of the input of cold energy, avoid the loss of cold energy during the transmission process, and improve the utilization efficiency of cold energy.

[0044] The cold source fluid enters the outer ring portion 41 through the inlet portion 411 for preliminary cooling, and then turns to enter the inner ring portion 42 for deep cooling. The inner ring portion 42 is closer to the interior of the main body 21 where the conduction section 11 penetrates. The temperature of the inner ring portion 42 is lower than that of the outer ring portion 41. The greater the cooling efficiency of the cold source fluid when it flows through the inner ring portion 42, when the cold source fluid finally flows from the inner ring portion 42 to the outlet portion 421 and leaves the shell 30, it can ensure that the temperature of the cold source fluid reaches and is maintained at the lowest point required for treatment, thereby ensuring to the greatest extent that the temperature of the cold source fluid at the outlet portion 421 reaches the lowest.

[0045] Specifically, Figure 1 and Figure 2 and Fig.10 As shown, the refrigeration device 10 includes: a cooling generator 12, a conduction seat 13 configured on the cooling generator 12 and connected to the shell 30, the conduction seat 13 constructs a conduction section 11, and the portion of the conduction section 11 extending into the interior of the main body 21 forms a conduction head 14. The cooling generator 12 supplies cold energy to the cooling system 100 and maintains the required low temperature state. The cooling generator 12 is connected to the shell 30 through the conduction seat 13, and the conduction section 11 extends into the interior of the main body 21 and forms a conduction head 14, so as to ensure that the cold energy can be efficiently and directionally transmitted from the cooling generator 12 to the core area of ​​the energy conversion component 20, and then the energy conversion component 20 accurately controls and distributes the cold energy to be transferred to the pipeline unit 40, thereby reducing the heat loss during the cold energy transmission process and ensuring the maximum utilization of the cold energy.

[0046] Further, Figure 2 and Fig. 9As shown, the pipeline unit 40 is configured as at least one cooling pipeline 401 or as a plurality of cooling pipelines 401 arranged in parallel. The pipeline unit 40 can be expanded to three, four, etc. according to actual needs to adapt to different cooling requirements. The parallel arrangement of multiple cooling pipelines 401 can optimize the flow path of the cold source fluid, promote the orderly and efficient convection of cold between the multiple cooling pipelines 401, and increase the cooling contact area to enhance the cooling efficiency.

[0047] Further, Figure 2 and Figure 3 As shown, the main body 21 is provided with a plurality of support parts 22 at equal intervals along the circumferential direction, and the shell 30 is constructed with a cooling rod 31 that penetrates the support part 22 in the longitudinal direction and is formed between the outer ring part 41 and the inner ring part 42. The support part 22 is provided with a mounting hole 28 in the longitudinal direction, and the cooling rod 31 is inserted into the mounting hole 28 to fix the energy conversion assembly 20 in the shell 30. The support parts 22 distributed at equal intervals provide necessary mechanical support for the energy conversion assembly 20 and enhance the overall structural stability of the energy conversion assembly 20; and cooperate with the cooling rod 31 to strengthen the connection between the shell 30 and the main body 21, and support and stabilize the circumferentially wound pipe unit 40. The cooling rod 31 can guide the cold energy to be smoothly transferred to the support part 22 in the longitudinal direction, ensuring the uniform distribution and effective transfer of the cold energy in the main body 21. Furthermore, the cooling rod 31 is located between the outer ring portion 41 and the inner ring portion 42 , which can promote uniform distribution of cooling energy inside the shell 30 and improve the indirect cooling effect on the cold source fluid flowing through the outer ring portion 41 and the inner ring portion 42 .

[0048] Further, Figure 2 As shown, the shell 30 is connected to one side of the refrigeration device 10 to form an interlayer chamber 32 for accommodating part of the conduction section 11. The shell 30 is constructed to accommodate a cooling chamber 33 for accommodating the energy conversion component 20, and the interlayer chamber 32 is isolated from the cooling chamber 33 by a partition 34. The cooling chamber 33 contains a refrigerant, and the interior of the interlayer chamber 32 is set to a vacuum state. By protecting part of the structure of the conduction section 11 through the interlayer chamber 32, the heat conduction and convection loss of the conduction section 11 to the outside can be reduced, and the loss of cold energy during the transmission process can be reduced, ensuring that the conduction section 11 can stably maintain the required low temperature level and is not affected by the temperature fluctuation of the external environment, so that the cold energy generated by the refrigeration device 10 can be more concentrated and efficiently used for the cold source fluid, thereby improving the energy efficiency of the cooling system 100. In addition, the interlayer chamber 32 can play a good protective role on the conduction section 11, avoiding corrosion or oxidation of the conduction section 11 by external factors such as moisture and oxygen, extending its service life, and enhancing the safety performance of the cooling system 100.

[0049] In some embodiments, illustratively, Figure 3As shown, the energy conversion assembly 20 further includes: a plurality of weight reduction grooves 26 that penetrate part of the main body 21 and extend to the top of the main body 21. The weight reduction grooves 26 can reduce the overall weight of the energy conversion assembly 20, reduce the amount of material used, and control costs.

[0050] It should be noted that the cryogen in the present embodiment includes but is not limited to liquid and gas. Exemplarily, the cryogen includes but is not limited to water, ethylene glycol, air, inert gas, carbon dioxide, nitrogen, helium, sulfur hexafluoride, ionic solution (e.g., sodium chloride containing or not containing potassium ions and other ions), glucose solution, Ringer's lactate solution, organic chemical solution (e.g., ethylene glycol, diethylene glycol or propylene glycol), oil (e.g., mineral oil, silicone oil, fluorocarbon oil), liquid metal, Freon, methyl halide, liquefied propane, other halogenated alkanes, anhydrous ammonia, sulfur dioxide, one or more or a combination thereof.

[0051] Combination Figures 1 to 11 As shown, the present invention also provides a cooling method using the above cooling system 100, comprising the following steps:

[0052] Step S1, start the refrigeration device 10 to generate cold energy, and introduce the cold energy into the energy conversion component 20 through the conduction section 11; the conduction section 11 extends axially into the interior of the main body 21, so that the cold energy generated by the refrigeration device 10 can be directly and efficiently transferred to the center of the energy conversion component 20, so that the energy conversion component 20 can transfer cold energy to the pipeline unit 40 and the refrigerant.

[0053] Step S2, guiding the cold source fluid into the pipeline unit 40, the cold source fluid flows around the energy conversion component 20 in the pipeline unit 40, and transfers cold energy to the pipeline unit 40 through the energy conversion component 20 to reduce the temperature of the cold source fluid; the energy conversion component 20 transfers cold energy to the pipeline unit 40 through the support portion 22, and the cold source fluid enters the outer ring portion 41 through the inlet portion 411 for preliminary cooling, and then turns to enter the inner ring portion 42 for deep cooling. Since the inner ring portion 42 is closer to the inside of the main body 21 where the conduction section 11 penetrates, the temperature of the inner ring portion 42 is lower than that of the outer ring portion 41. The cooling efficiency of the cold source fluid when flowing through the inner ring portion 42 is stronger. When the cold source fluid finally flows from the inner ring portion 42 to the outlet portion 421 and leaves the shell 30, it can ensure that the temperature of the cold source fluid reaches and is maintained at the lowest point required for treatment, thereby ensuring to the greatest extent that the temperature of the cold source fluid at the outlet portion 421 reaches the lowest.

[0054] Step S3: The cold source fluid cooled by the energy conversion assembly 20 is led out by the pipeline unit 40 .

[0055] In addition, the excess cold is transferred to the refrigerant through the cold conversion assembly for cold storage. The above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any technician familiar with the technical field can easily think of changes or replacements within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
